Most of us have learned over time to wipe our feet before entering the house. This spring, Natural Resource Specialist Kristen Sinclair will put a new spin on this message with the installation of three boot brush stations at Lake Fairfax Park. The goal of the one-year pilot project is to stop the spread of non-native invasive plant species such as wavyleaf basketgrass and garlic mustard by removing unwanted seeds from the soles of hikers’ shoes and boots.

Boot brush stations have been installed successfully by park agencies in the Midwest and the National Park Service. The Lake Fairfax stations will be located at trailheads and near the campground. Stations include a framed educational sign, mounted boot brush, and a gravel reservoir to catch fallen seeds. To deter new weeds from sprouting up in the soil around the stations, a pre-emergent herbicide will be applied to the gravel area.

Funded by the Fairfax County Board of Supervisors’ Environmental Improvement Program, the stations provide an opportunity to educate park users about the negative effects of non-native invasive plants on the local environment. Aggressive invaders can choke forests, suppress native plants, and damage wildlife habitat. A startling example of invasive species spreading unchecked on parkland can be found at Maryland’s Patapsco Valley State Park, where wavyleaf basketgrass engulfed 100 acres in less than 10 years.

Wavyleaf Basketgrass

The threat of this happening at Lake Fairfax is very real. Erin Stockschlaeder, coordinator for the Invasive Management Area (IMA) and Early Detection and Rapid Response (EDRR) programs, has discovered and mapped wavyleaf basketgrass in the park. This plant blankets the forest floor, and its small, sticky seeds cling to pant legs, socks, and boots. As the invading plant spreads, native plants including deer’s tongue (a native grass), violets, trout lilies, and a variety of ferns disappear. According to Sinclair, one measure of success for the program would be finding no new populations of wavyleaf basketgrass in the campground or on the trails. If the program is deemed successful, brush stations may be installed at other parks throughout the system.

A sign identifies common invasive species.

Getting the most bang for your buck is important in these lean budget years, and once installed the new inexpensive brush stations will require little maintenance. Three brush station kits and sign will be purchased from Genesis Graphics of Escanaba, Michigan, and assembled and installed by Groundskeeper Specialist Ferlin Mathews and the Area 6 crew. Graphics for the sign were developed by Graphic Designers Joanne Kearney and Alex Ngyuen. “We will monitor the stations the first season to make sure there aren’t any undue maintenance issues,” said Sinclair.

When implemented, this project will accomplish one of 12 best practices to assist in the prevention, control, and eradication of non-native invasive plan species, as recommended in the Park Authority’s 2009 Natural Resource Management Plan. Sinclair concluded, “I believe an interactive sign is a great way to raise awareness of the issue of “hitchhiking seeds.” It certainly can’t make the problem any worse.”

Trail Program Manager Liz Cronauer speaks at the 2010 opening of the Clarks Branch Crossing bridge in Riverbend Park.

Liz Cronauer, trail program manager for the Fairfax County Park Authority, recently updated members of Fairfax Trails and Streams (FTAS) on the agency’s Trail Development Strategy. Cronauer visits the group at least once a year to discuss completed trail projects and future connections. FTAS’s primary focus is on trails in Great Falls and McLean, but they’re also interested in seeing the completion of the Potomac Heritage National Scenic Trail (PHNST) in southern Fairfax County, which, according to Cronauer, could be completed within the next decade. “This is a good crowd of people to talk to. They’re all pro trails, and members have lots of ideas,” she said.

Trails are consistently ranked as the most popular park amenity by Fairfax County residents. According to Cronauer, the reason trails are liked so much is because trails appeal to such a wide range of people. “You can use them for walking, cycling, and bird watching. All ages use trails, and they’re free,” she said. “There is a big demand for passive recreation,” she continued. (Although most recreational pursuits on trails are considered active, trails are officially classified as passive recreation. Organized facilities such as ball fields and swimming pools are classified as active recreation areas.)

Flooding from remnants of Tropical Storm Lee ravaged trails throughout the county last September.

In September 2011, the remnants of Tropical Storm Lee ravaged Fairfax County, and some areas within the Park Authority’s stream valley trail network were washed away. “Significant damage remains,” said Cronauer. She said the damage was so extensive in some places that the short term goal of the Park Operations Division was to simply make the trails functional again rather than restore them to their original condition. In certain places the damage was severe. It will take a little longer to restore functionality in those areas. “Long Branch Stream Valley was hit hard, specifically the bridge. A bridge needs to be replaced and plans are now in place to move that project forward in the next 12 to 18 months. Part of the trail along Difficult Run has also been severely damaged. Parks Ops has done a tremendous amount of work and replaced tons of stone,” Cronauer said. Repairs to trails throughout the county continue.

The Cross County Trail connects the Potomac River in the north to the Occoquan River in the south.

Although the Park Authority is always trying to add new trails, Cronauer said it’s important to “improve areas that we already have.” She’s always looking for ways to forge new connections to the Cross County Trail (CCT), the 41.5-mile trail which links Great Falls Park in the north to Occoquan Regional Park in the south. In 2010, the Park Authority completed the Barbara Lane connector trail, which made it easier for people in the eastern Mantua neighborhood to access the CCT. Cronauer said future trail connections include “fixing the footpath within Mount Vernon District Park along Fort Hunt Road.” Once this trail has been improved, people will be able to safely walk and bicycle to Mount Vernon RECenter. There are also plans to improve the South Run Stream Valley trail by paving the section that traces the north side of Lake Mercer and connecting it to South Run RECenter. “Any time you can create ways for people to bicycle to a RECenter is just great,” Cronauer said.

The Lake Fairfax trail network continues to grow.

The 2012 Park Bond, still to be authorized and then potentially approved by voters, allocates additional funds for trail improvements. The Park Authority Board will decide where to spend the money if Fairfax County citizens pass the bond. Cronauer hopes to see funding for some particular trail projects noting, “Pohick Stream Valley is one of the last major stream valley trail areas that hasn’t been completed. That would be a high priority for me because we could make a really good connection to the Cross County Trail. Additionally, we would like to finish the trail network at Lake Fairfax Park.”

The Park Authority is regularly approached by volunteers with an interest in trail building and maintenance. Cronauer said “The best way for them to be involved is through a trails group. The Park Authority coordinates with trails groups such as M.O.R.E. (Mid-Atlantic Off-Road Enthusiasts) and FTAS, and they manage volunteers and coordinate with area managers to identify projects. Together they get a lot of work done.”

Cronauer was hired as the trails program manager in October 2005, when the Park Authority created the position. She leads a small team of two project managers.

As a resident of Prince William County, Cronauer spends a lot of time in majestic Prince William Forest near Quantico, but she has her favorite trails in Fairfax County, too. “I really love the section of the CCT in the Pohick Stream Valley and all the Riverbend Park trails. I also like the single track trails we built in Laurel Hill,” she said.
